UNAVCO/WInSAR, the Alaska Satellite Facility (ASF), and JPL collaborated in an information technology and data management development project to design and implement a seamless distributed access system for Synthetic Aperture Radar (SAR) data and derived data products (InSAR interferograms). A seamless SAR archive increases the accessibility and the utility of SAR science data to solid Earth and cryospheric science researchers. Specifically, the project provides simple web services tools to more seamlessly and effectively exchange and share SAR metadata, data and archived and on-demand derived products between the distributed archives, individual users, and key information technology development systems such as the NASA/JPL ARIA projects that provide higher level resources for geodetic data processing, data assimilation and modeling, and integrative analysis for scientific research and hazards applications.
The final Seamless SAR Archive (SSARA) significantly enhances mature IT capabilities at ASFs NASA-supported DAAC, the GEO Supersites archive, supported operationally by UNAVCO, and UNAVCO’s SAR data archive that are supported by NASA, NSF, and the USGS in close collaboration with ESA/ESRIN. As part of the effort, data/product standard formats and new QC/QA definitions were developed and implemented to streamline data usage and enable advanced query capability.
SSARA provides users with simple browser and web service API access tools to view and retrieve SAR data from multiple archives, to place their tasking requests, to order data, and to report results back to data providers; to make a larger pool of data available to scientific data users; and to encourage broader national and international use of SAR data. The ACCESS-developed tools help overcome past obstacles including heterogeneous archive access protocols and data/product formats, data provider access policy constraints, and an increasingly broad and diverse selection of SAR data that now includes ESA/ERS/ENVISAT (and upcoming Sentinel mission), CSA/Radarsat, JAXA/ ALOS-PALSAR, DLR/TerraSAR-X satellite data and NASA/UAVSAR aircraft SAR data.
